Abstract

Aromatic aldehydes undergo crossed aldol condensation with cyclic ketones in the presence of Y (TFA) 3 under solvent-free conditions to afford the corresponding α, α'-bis (substituted benzylidene) cycloalkanones in satisfactory yields. Furthermore, the catalyst can be recovered conveniently and reused several times in the reaction with comparable yields.
